Problem solved ... with common electrical tape! I'm sure about a million people have thought of this already, but there's no such thing as too much knowledge. What I did was cut a very small square of it and put it over my web cam lens. Since this type of type is not very sticky, I can easily take it off when I need the web cam (almost never) and even reapply it when I'm done using it.
My laptop is black so the piece of tape isn't even visible enough to worry about looking cheesy. But if you have a different colored machine, you can even purchase other colors of electrical tape. So if you have an Apple and use it in a professional setting, you could buy white electrical tape and nobody will even be able to see (unless they really look, which is creepy anyway) that you have your camera covered.
